Another comment author, Kasvio, provided a richer portrait of Terence and his modus operandi, to which I posted the following response:

Thank you for writing that comment, Kasvio. It amazes me that anybody could garner as much information about the specifics of the Timewave model and yet remain so oblivious to the general themes of Terence’s larger message. To label Terence McKenna as “New Age” requires complete ignorance of the history of what has come to be called the New Age movement, ignorance of Terence’s motivations and intentions, or a willingness to sweep nuance and inconvenient data under the rug. This last describes so many self-styled “skeptics” that Robert Anton Wilson coined a new term, zeteticism, to describe actual skepticism and differentiate it from the irrational rationalism that has camped under the banner of skepticism.

I doubt that any self-identified "skeptic" would take the time to listen to the full "In the Valley of Novelty" series of lectures, but most anyone who does so will soon grok why the "skeptic" who takes the time to "debunk" Timewave Zero is akin to someone who destroys a carp-shaped paper lantern with a shotgun thinking that he's shooting fish in a barrel.
